The effectiveness of 1-NAA and 2, 4, 5-T in markedly retarding further ripening of pineapple fruit and thus extending its marketable life as a fresh fruit was demonstrated. The effects were evident at different stages of maturity and ripeness, different fruit densities, and from both pre-harvest and post-harvest applications. As little as 1 p.p.m. of 2, 4, 5-T had a noticeable effect, and 100 p.p.m. was optimal for retarding senescence.
